Grapevine ‘IFG Fourteen’

ABSTRACT

This invention is a new and distinct grapevine variety named ‘IFG Fourteen’ which is characterized by producing small round bright red berries having very crisp texture with a very strong muscat flavor and which ripens in midseason.

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘IFG Fourteen’.

BACKGROUND OF THE INVENTION

The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the IFG 01077-096-221, an unnamed seedless selection from the IFG breeding program and the IFG 01054-082-202 another unnamed seedless selection from the IFG breeding program hybridized in May 2004. The abortive seed traces were subsequently embryo cultured and the resulting plant was planted in the field in April 2005. The present variety of grapevine was selected as a single plant in 2006 and was first asexually propagated by hardwood cuttings in December 2006 near Delano, Kern County, Calif. The resulting propagules were planted during April 2007 near Delano, Kern County, Calif. and were found to reproduce true-to-type through at least two generations of asexual reproduction using hardwood cuttings and grafting onto rootstocks.

BRIEF SUMMARY OF THE INVENTION

The new grapevine ‘IFG Fourteen’ is characterized by producing small round bright red berries having very crisp texture with a very strong muscat flavor and which ripens in midseason. Berries are borne on small to medium size clusters which are very compact and require gibberellin applications to thin clusters and size berries. Berries color extremely well and do not require chemical applications to achieve good color. ‘IFG Fourteen’ stores extremely well. Stems remain green and berries retain their crisp texture and strong muscat flavor for up to twelve weeks in cold storage. To the inventor's knowledge, the known variety to which the new grapevine variety is most similar is the Flame seedless variety (unpatented). ‘IFG Fourteen’ differs from the ‘Flame Seedless’ by ripening approximately three to four weeks later, having less waxy bloom and having a very strong flowery muscat flavor as opposed to the neutral flavor of ‘Flame Seedless’.

‘IFG Fourteen’ differs from its maternal parent by producing brighter red, crisp berries that have a strong muscat flavor as opposed to the softer reddish black later ripening neutral flavored fruits of the IFG 01077-096-221. It differs from its pollen parent, by having later ripening, crisp red, muscat flavored berries as opposed to the early ripening black berries of the IFG 01054-082-202.

The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG Fourteen’. The colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED BOTANICAL DESCRIPTION OF THE INVENTION

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England.

Throughout this specification subjective description values conform to those set forth by the International Plant Genetic Resources Institute publication ‘Descriptors for Grape’ (Vitis spp.) (1983) which was developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).
